Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Null pointer dereference (CVE-ID: CVE-2018-11356)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in epan/dissectors/packet-dns.c due to NULL pointer dereference. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file and cause the DNS dissector to crash.
2) Resource exhaustion (CVE-ID: CVE-2018-11357)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in epan/tvbuff.c due to improper validation of user-supplied input. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file, trigger resource exhaustion and cause the LTP dissector and other dissectors to crash.
3) Use-after-free error (CVE-ID: CVE-2018-11358)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in epan/dissectors/packet-q931.c due to use-after-free memory error. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file, trigger memory corruption and cause the Q.931 dissector and other dissectors to crash.
4) Null pointer dereference (CVE-ID: CVE-2018-11359)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in epan/proto.c due to NULL pointer dereference. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file and cause the RRC dissector and other dissectors to crash.
5) Buffer overflow (CVE-ID: CVE-2018-11360)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in epan/dissectors/packet-gsm_a_dtap.c due to off-by-one error. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file, trigger buffer overflow and cause the GSM A DTAP dissector to crash.
6) Buffer over-read (CVE-ID: CVE-2018-11362)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in epan/dissectors/packet-ldss.c due to buffer over-read upon encountering a missing '' character. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file, trigger memory corruption and cause the LDSS dissector to crash.
